One of the point of having a hardware accelerator is that your CPU can do something else while your GPU/FPGA/whatever hashes. It is right now not trivial to do such a thing with JtR. It would however be great to be able to generate candidate passwords and perhaps prepare them, handle memory transferts on the CPU side, and just hash on the GPU side. If you really want to do it using the current interface, you'll have your GPU waiting while the CPU is working, and the other way around. There is a way to hack something that would be much better, but it would require also hacking the self tests. -- To unsubscribe, e-mail john-users-unsubscribe@...ts.openwall.com and reply to the automated confirmation request that will be sent to you.
